This option should ONLY be used if there is no way the customer can send the AutoSupport outside of their environment. By not sending the AutoSupport to NetApp, the customer is not able to take advantage of our reactive capabilities like case creation and auto parts replacement, nor our proactive capabilities such as health checks and risk notifications.
This should be a last option for secure environments.
Please contact me offline if this is not the case and there are other reasons.
